Fragmented Impact Melt

Western floor of the fresh crater Giordano Bruno, LROC Narrow Angle Camera M110919730L, 0.61 m/pixel, field of view is about 737 meters, illumination is from the lower right, at an incidence angle of 42° View the full-sized image HERE [NASA/GSFC/Arizona State University].

Today's Featured Image looks like a parched Arizona mudflat after a monsoon downpour. Not quite! You are looking at the broken surface of an impact melt pond inside Giordano Bruno crater. A surface crust fragmented into angular blocks up to about 40 meters in width as still molten rock was drained from beneath a hardening crust. The small clusters of relatively bright rock fragments are likely boulders that rolled down from the nearby steep walls.
